The correct Answer is:
To find the distance between the origin (0, 0) and the point (-8, 6), we can use the distance formula. The distance formula is given by: \[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \] Where: - \((x_1, y_1)\) is the first point (the origin in this case), - \((x_2, y_2)\) is the second point (-8, 6). ### Step 1: Identify the points - Let the origin be point A: \((x_1, y_1) = (0, 0)\) - Let the point (-8, 6) be point B: \((x_2, y_2) = (-8, 6)\) ### Step 2: Substitute the coordinates into the distance formula Using the distance formula: \[ d = \sqrt{((-8) - 0)^2 + (6 - 0)^2} \] ### Step 3: Simplify the expression Calculate the differences: \[ d = \sqrt{(-8)^2 + (6)^2} \] ### Step 4: Calculate the squares Now calculate the squares: \[ d = \sqrt{64 + 36} \] ### Step 5: Add the squares Add the results: \[ d = \sqrt{100} \] ### Step 6: Calculate the square root Now take the square root: \[ d = 10 \] ### Final Answer The distance between the origin and the point (-8, 6) is **10 units**. ---
